42889-91-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 42889-91-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,8,8 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 42889-91:
(7*4)+(6*2)+(5*8)+(4*8)+(3*9)+(2*9)+(1*1)=158
158 % 10 = 8
So 42889-91-8 is a valid CAS Registry Number.

Programmed photodegradation of polymeric/oligomeric materials derived from renewable bioresources

Rajendran, Saravanakumar,Raghunathan, Ramya,Hevus, Ivan,Krishnan, Retheesh,Ugrinov, Angel,Sibi, Mukund P.,Webster, Dean C.,Sivaguru, Jayaraman

, p. 1159 - 1163 (2015)

Renewable polymeric materials derived from biomass with built-in phototriggers were synthesized and evaluated for degradation under irradiation of UV light. Complete decomposition of the polymeric materials was observed with recovery of the monomer that was used to resynthesize the polymers.

PRODRUG AND PROTECTED FORMS OF 5-HYDROXYMETHYLFURFURANAL (5-HMF) AND ITS DERIVATIVES

-

Page/Page column 34, (2018/02/27)

Prodrugs and derivatives of 5-hydoxymethyl-2-furfural (5-HMF) with protected or modified aldehyde and/or alcohol moieties are provided. The prodrugs or derivatives exhibit increased bioavailability, e.g. due to having extended half-lives in circulation. The drugs are therefore administered i) at lower doses and/or ii) less frequently than 5-HMF, while still maintaining the beneficial therapeutic effects of 5-HMF.

Palladium-catalyzed regioselective allylation of five-membered heteroarenes with allyltributylstannane

Zhang, Sheng,Yu, Xiaoqiang,Feng, Xiujuan,Yamamoto, Yoshinori,Bao, Ming

supporting information, p. 3842 - 3845 (2015/03/30)

Palladium-catalyzed allylation reactions of 2-(chloromethyl)thiophenes, 2-(chloromethyl)furans, and N-protected 2-(chloromethyl)-1H-pyrroles with allyltributylstannane were described in this study. This type of allylation reaction regioselectively occurred on the heteroarene rings to produce allylated dearomatization products or allylated heteroarenes with satisfactory yields.
